We analyze the entanglement spectrum of Laughlin states on the torus and show that it is arranged in towers, each of which is generated by modes of two spatially separated chiral edges. This structure is present for all torus circumferences, which allows for a microscopic identification of the prominent features of the spectrum by perturbing around the thin-torus limit.
我们分析了环面上 Laughlin 态的纠缠谱，发现它是按塔的形式排列的，每个塔由两个空间分离的手性边缘模式产生。这种结构对于所有环面周长都存在，这使得通过在薄环极限附近微扰，可以对谱的显著特征进行微观识别。
